Origin Story
北魏时期，有个叫封轨的官员，他为人正直，勤奋好学，非常重视个人仪容，总是衣冠楚楚。一天，一位蓬头垢面的学者见到他，不屑地说："真正有学问的人，才不会在乎这些外在的东西呢！"封轨笑了笑，说："君子正其衣冠，尊其瞻视，这并非虚礼，而是对自身的一种尊重，也是对别人的尊重。我们更应该注重内在修养，但也不能忽视外在形象。"这位学者听后，羞愧地低下了头。从此，他开始注意自己的仪表，不再蓬头垢面了。
During the Northern Wei Dynasty, there was an official named Feng Gui, known for his integrity and diligence. He was very meticulous about his appearance and always dressed impeccably. One day, he encountered a scholar who was disheveled and dirty. The scholar disdainfully remarked, "True scholars don't care about such superficial things!" Feng Gui smiled and replied, "A gentleman pays attention to his clothing and appearance; it's not mere formality, but a form of self-respect and respect for others. We should focus more on inner cultivation, but we shouldn't neglect our outward appearance." The scholar hung his head in shame. From that day on, he began to pay attention to his appearance and was no longer unkempt.
